To a'ltwhom it may concern;

Be it known that I, DANIEL ML Tum, of-JCanastota, in the county of Madison and Stateof New York, have invented a certain gine, of which the following i a sped-flew tlon. v My'inv'ention relat to v e n l the arrangement of inlet and exhaust ports combinations and constructions hereinafter seti'orth and claimed.

Indescribing thisinvention reference is held to the accompanying drawing-in which characters c designate corresponding parts in allthe views. I Figureslc and 2 are-vertical sectionsof myzengine taken at a right angle to each other, F 3 is. a horizontal section, partly is an elevation of the piston, 1 is-the cylinder;' 2, the piston-movable the cylinder;- 3, the journaled in) beatings; provided inth'e crank case 4; and 5,;a' pitman connectingfthe piston 2 and as a a rear compression chainher for 'the mo ti've-flnid,'-in' the ordinary manner, but so far as my invent-ion is eencemed, the motive fluidvmay hey-supplied to thecy linder from 1 v I H 'andexhaust ports of my engine-,the cylin any other source. An igniter, ,as a spark concentration of. the inflowing mixture for igniting such mixture after compression.

- Thecylintier isclos'ed "at its inner end and s'tantia'l'ly diametrically opposite to each the inlet. "6 and substantially ,dia-met- 6 and exhaust ports .7 located near, and in from; of, the position occupied by the head of'the piston when as pistoh is at the limit of "-its' outstrok, order that the flow. through the ports, is controlled by the interior of the crank case by conduits 8 which, as-here shown, open into the portion g ends of thecondu' 8 when the the end of its outstroke.

10 which occupy a'position in front of the inlet ports'6 when the pistonis at thefllimit of ts outstroke in order that the incoming chargewill be directed toward the inner end (of the cylinder. Each deflector 10 is preferably formed with sides 11 which extend-toward the inlet port 6 with which it 00- f operates, said. sides 11 converging from the piston' toward the end. of. the deflector so that the charge'entering the port 6 is choked and is injectedztoward the inner end of the fl ector: were un rovided with converging 1 Sides. The pis on is alsoprovided ,with

inner end'of the. cylinder and being directedhyleach other toward the piston alongthe axis of the .cylinder,'the columns having a gswirling motion during, such movement to- -itsswirling motion toward the piston qu ckly and thoroughly expels the burned gases. v

- Owing to the, arrangement of theinlet i der is-more thoroughly scavenged-a larger 'the enginedevlops more power than an inare arranged in the ordinary manner.

t'ion, taken 'infconnection with the drawings, that when the piston is in its extreme outward stroke, the deflectors -l1- cover the inner ends of the inlet por s I in close proximity thereto and extend some distance inwardly ,h'eyond said substantially der, so as'to confine the-inflowingfmixture thereby (causing the mixture to travel{'upwardly along the sides and to the extreme top-or outer end-of the cylinder "where the inflowing currents meet above the spent gasesand preduce a-dewnward pressure'opthe "trunk of the piston being formed with passages 9 which register with lower tie expel such "s ent piston is at The pistonQ-isprovided with deflectors i downwardly. diverging deflectors l2lmeeting g l 75 the cy inder, these columns meeting at the ternal combustione i g ne in which the ports It will be seen from the foregoing descripiparallel with the adjacent sides of thebylin cyli nder with greater force than if the ides =ward the piston. The incoming charge durcharge and,a better mixture isohtai'ned, and

against the adjacent sides of the cylinder, 1

gases downwardly and outwardly through the exhaust ports. In other words, by con- 1 fining the two inflowing currents of explosive mixtures against opposite sides of the cylinder, these currents operate to force the spent gases toward the center, and when the inflowing currents meet at the top their combined pressures are centralized or balanced, and constitute in efiect a downwardlv moving piston acting upon the spent gases as a body to expel the latter downwardly 4 and outwardly through the exhaust ports,

thus effectively filling the chamber with live trolling said ports and provided with diametrically opposite deflectors substantially parallel with and in close proximity 'to the adjacent sides of the cylinder and extending across and inwardly beyond the inner ends of the inlet ports when the piston is at the limit of its outward stroke for directing the infiowing mixture away from the center and along the adjacent sides of the cylinder at opposite sides of theigniting device- 2. In an' internal combustion engine, a cylinder, and a piston movable in the cylinder, the cylinder having inlet ports located substantially diametrically opposite to each other,

and exhaust ports disposed between the inlet ports and located substantially diametrically opposite to each other, the inlet and exhaust ports being located near and in front of the position occupied-by the piston-head when the piston is at the limit of its outstroke, and the piston being provided with deflectors located near its edge and arranged to be brought opposite to the inlet ports as thepiston approaches-theliniit of its outstroke, and thereby deflect the incoming charge along the sides of the cylinder to the inner end of the cylinder, and the piston-head being also provided with oppositely inclined deflectors slanting toward the edge of the piston and arranged to be brought opposite to'the exhaust ports as the piston nears the limit ofits outstroke, substantially as and for the purpose described.

7. In a two-cycle internal-combustlon engine, a cylinder having diametrically opposite mixture inlet ports and opposite exhaust ports located between the inlet ports, an igniting device centrally in the head of the cylinder, a piston controlling said ports, means on the head of the piston close to the sides of the cylinder for preventing the passing of such mixture from the inlet ports to the center of the piston head and for causing said infiowing mixture to travel along the sides to the head of the cylinder whereby the opposite inflowing currents of the mixture are caused to meet at the igniting device.

8. In a two-cycle internal-combustion engine, a cylinder, a piston movable in the cylinder, deflectors on opposite sides of the head of the piston''close to the adjacent sides of the cylinder and spaced some distance apart, said cylinder being provided with inlet ports in the sides thereof adjacent to the deflectors and arranged to be opened simultaneously at the end ofthe working stroke and also provided with exhaust ports registering with a space between the deflectors when the piston is at the limit of its outward stroke.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 15th day of April, 1909.
